ABSTRACT:
A vibrator motor has an armature rotor whose center of mass is off the axis of the shaft thereof. The rotor includes at least three poles each having an winding arm and an arcuate pole blade. All of the blades have an equal length and are disposed angularly evenly about the axis of the shaft so that all of the blade-to-blade spacings are equal. At least one winding arm is angularly out of alignment with the dimensional center of the arcuate blade of the corresponding pole, or, the size and the mass of at least one arm is different from those of any other arms, or, the mass of at least one of armature windings is different from the mass of any other armature winding, or, a weight is fixedly attached to the rotor in an eccentric manner either between two armature poles or on the shaft.
